CVE-2026-48156 MEDIUM PATCH This Month

Denial-of-service via algorithmic complexity in pypdf before 6.12.0 allows an attacker who can supply a crafted PDF file to cause excessive processing time during cross-reference stream parsing. The vulnerability is triggered by crafting a PDF with /W [0 0 0] field values in a cross-reference stream combined with a large /Size value, which causes the library to perform unbounded iteration over zero-byte entries. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, any application that processes untrusted PDF input using pypdf is exposed.

CVE-2026-41313 PyPI MEDIUM PATCH This Month

Denial of service via algorithmic complexity in pypdf versions prior to 6.10.2 allows local attackers to cause long runtimes by crafting a PDF with an excessively large trailer /Size value when loaded in incremental mode. The vulnerability requires user interaction to load the malicious PDF and results in availability degradation rather than data compromise. Patch version 6.10.2 is available from the vendor.

CVE-2026-41168 PyPI MEDIUM PATCH This Month

Denial of service in pypdf prior to version 6.10.1 allows remote attackers to craft malicious PDF files with oversized cross-reference stream `/Size` values or object stream `/N` values, causing excessive processing time and long runtimes. No authentication is required; the vulnerability is triggered by parsing a specially crafted PDF file. Patch version 6.10.1 is available from the vendor.

CVE-2026-27025 PyPI MEDIUM PATCH This Month

Resource exhaustion in pypdf versions prior to 6.7.1 occurs when processing maliciously crafted PDF files with manipulated /ToUnicode font entries, causing excessive memory consumption and processing delays during text extraction operations. A local attacker with file access can exploit this to degrade system performance, though no code execution or data compromise is possible. The vulnerability affects Python environments using pypdf and is remedied by upgrading to version 6.7.1 or later.
